The Gombak-Hulu Langat Geopark includes the Artesian Hot Water Well, Kampung Jawa, which is located in the villages of Jawa Batu 18 and Kampung Sungai Serai and possesses scientific, recreational, aesthetic, and cultural heritage values. This hot water is trapped beneath a layer of granite rock, and drilling allows the trapped water to reach the surface.
These geosites are the result of anthropogenic or human-caused activity during the drilling process. The volume of hot water that flows out of this 160-foot-deep well is the greatest in Malaysia, with temperatures ranging from 47 to 49 degrees Celsius (°C). The development of int hot water is linked to the entry of surface water through a series of fissures along the Kuala Lumpur and Bukit Tinggi Faults, which are heated near the mantle.
Currently, the geosite serves as an ablution place for the mosque, but the long term goal is to promote tourism based hot springs and to be used by the local community.
This is Gombak-Hulu Langat Geopark’s geosite (G31)
